This is a Timestamp, that represents itself as UTC.
|
|
|
41 |
Internally it stores exactly the same value as Timestamp,
|
|
|
42 |
so the following experssion is always true:
|
|
|
43 |
|
|
|
44 |
someTimestamp asUtcTimestamp = someTimestamp asLocalTimestamp
|
|
|
45 |
|
|
|
46 |
But when printing, accessing hour, minute, ... and converting to Date and Time,
|
|
|
47 |
it returns the values represented in the UTC zone instead of the local timezone.
